Book excerpt: The Spice Islands Voyage is about a journey and a quest: a journey among the Spice Islands of equatorial Indonesia aboard a traditional native sailing vessel; a quest to rediscover Alfred Russel Wallace, the brilliant and intrepid naturalist who jointly proposed, with Charles Darwin, the theory of natural selection, and whose travels founded the science of zoo geography. Navigating through sparkling coral seas to remote shorelines, Tim Severin and his crew retraced the explorer's journeys, encountering green turtles and flying foxes, observing the smuggling of rare birds and rainforest destruction, but also witnessing the emergence of a new sense of environmental awareness. 'Full of insights retraces a journey through places of fabulous natural and cultural diversity should inspire new readers to discover the remarkable writings of Wallace himself', Independent
